Citat:
If a communication problem occurs on a PVC (no traffic going one way or the other), the permanent virtual circuit (PVC) remains UP on the end-devices. Therefore, routing entries that were pointing to that PVC remain in the routing table for a certain time and as a result, packets will be lost. The solution to this problem is to use Operation and Maintenance (OAM) to detect such failures and allow the PVC to disconnect if it is disrupted along its path.
